Happy #BumpDay! It’s so exciting to watch your baby grow and experience all of their major milestones. Although each baby will grow and develop at different paces, each major milestone usually happens around the same age. Parenting magazine recently posted these important milestones that your baby should hit.

Here’s when the average baby’s development milestones happen, by age:

  • 8 weeks: Smiling. The first social skill your baby will learn is how to smile. At 8 weeks, their nervous system and vision develop enough for them to learn how to “social smile,” or recognize and react to different emotional states.
  • 2-3 months: Rolling over. During tummy time, your baby may push up on their arms and rock back and forth, eventually rolling themselves over. Rolling over shows coordination and strength, but you don’t need to coach your baby into it. Just make sure they have enough room to try it out.
  • 3-4 months: Grabbing. By 3 or 4 months, your little one should be able to figure out where objects are in space and can plan a course of action. At this stage, they can also start to engage in play and start to figure out cause and effect, like how picking up a toy will make it rattle.
  • 5 months: Hugging. By this age, infants learn to hug by observing other people and being hugged themselves. While some babies will be affectionate, others will be more preoccupied with exploring the world around them. Most will be more affectionate around bedtime or when you’re looking at a book together.
  • 6 months: Playing peek-a-boo. At 6 months, your baby will start to understand the concept of object permanence, meaning that even though they can’t see your face, they know it’s still behind your hands. This game is so entertaining for them because they’re anticipating when your face will pop back into view.
  • 8 months: Sitting/pulling up. By this time, your baby’s improving eyesight will allow them to see objects outside of their direct line of vision. With their newfound balance, arm strength and control, they’ll start to pull themselves up to get a better look. Once their leg and torso muscles become strong enough, they’ll also start to hold onto objects to fully pull themselves up.
  • 6-10 months: Crawling. Once your little one figures out they can support themselves, they’ll start to crawl. Some babies may opt for shuffling across the floor on their bottom, sliding on their belly or even rolling. Just make sure your home is baby proof and clear some space for them to explore.
  • 10-18 months: Walking. Your baby will combine all of these developments- including muscle strength, coordination, balance and confidence- to start walking. Some babies will cling to furniture for a few weeks, while others will go off on their own as soon as they can!
